LOOMQ SPECIFICATION forming pan: of Letters Patent No. 373,246, datedNovember 15, 1887.

Application filed May 27, 1886.

To all whom it may concern.-

Be it known that I, CHARLES N. N EwooMB, of Omaha, in the county ofDouglas and State of Nebraska, havev invented a new and usefulImprovement in Hand-Looms, of which the following is a full, clear, andexact description.

My improvements relate specially to handlooms for weaving rag carpets;and the invention consists in novel features of construction andarrangement of parts, as hereinafter described, and pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in, all the figures.

Figure 1 isavertical transverse section of a loom containing myimprovements. Fig. 2 is a plan view of the same. Fig. 3 is a rearelevation with the warp-beam partially broken away. Fig. 4 is a detailview, on an enlarged scale, of the means for operating the crankshaft,the cam on the end of the said shaft being of amodified form. Fig. 5 isa similar view viewed from the opposite side and with the Fig. 6 is adetail perspective view of one of the pickers and a portion of one ofthe picker-sticks.

In its general construction the loom is as usual.

A is the warp-beam; B B, the heddles,fitted to slide in guides g,- C,the vibrating lay, consisting of swords or side standards, a a, carryingbed band connected at their lower ends by a cross-bar, d.

D is the front or breast roller, and E the cloth-roller.

Upon longitudinal rails e is mounted a shaft, f, provided at one endwith a double crank, from which pitmen g pass to and are connected tothe heddles B. On the shaft is a ratchetwheel, h.

t dare arms having their outer ends bent over for the attachment of thesprings a. 11 i are shorter arms upon the opposite sides of theratchet-wheel h. Through the upper end of each pair of connecting-strapsZ Z, the end of the shorter arms, a" i, and the middle of the arms i iis passed a bolt, 2', which bolt forms the pivot of the pawl It, all asclearly shown in Figs. 4 and 5. Thelower ends of the four straps Z entera mortise in a bar, m, and are connected Serial No. 203,430. (No model.)

therewith by a bolt passing through the bar and straps. The bar 171. isfitted to slide verticall y on depending pins n, secured between thefixed rails e.

0 is an eccentric on shaftf between the arms of the forked upper end ofa piece, go, that is held to rail 6' by a cross-arm, b, attached bycleats or guides a, so as to permit side movement of the piece p, andthe lower end of the forked piece 19 strides a trigger, q, that is hungon the frame and passes through a loop, q,on the under side of the barm.

1' r are stirrups hung on the lower bar, d, of

the lay, with their lower ends bent inward toward the trigger q, andconnected at their up per ends to the picker-sticks s by straps t.Springs 15 are interposed between the stirrups and straps-and thestirrups are connected by a strap, t. The picker-sticks are pivoted onthe pinsu, on which the lay swings. The picker-sticks extend below theirpivots, and their lower ends can be connected by a cord, a, having aninterposed'spiral spring, 22', so that the pickerstickscan be held atthe outer ends of the boxes when not in use.

' On the back of the standards a of the lay triangles v are attached,and these are connected by short rods (1 to the slide-bar m, so as tocause the bar to rise and fall as the lay moves forward and back, andthus give movement to straps l and pawls is, so as to cause intermittentrotation of ratchet-wheel h. The wheel h is moved a half-revolution bythe action of the two pawls at each complete reciprocation of the lay,and the heddles thus shifted.

The rotation of the shaft f with wheel h causes the shifting of piece 10by eccentric 0, and the trigger q is thereby shifted above the bent endsof the two stirrups r alternately, sothat, the trigger being presseddown by beam m, the pick er-sticks s are operated in alternate order.

* The back beam, e, over which the warps pass, ishung on pivotsf,and isconnected bylooselyjointed arms g to the posts k, that project downbetween rails e, and are supported thereon by spiral springs i. When barm rises, as before described, it lifts the posts h slightly, therebymoving the beam 6 back far enough to strain thewarp just at the momentthe reed strikes the rag filling, which insures its being beaten upclosely. As the lay returns, the beam 0 comes forward again and thewarps are slacked enough to permit of the shed opening widely andeasily.

For giving tension to the warps, straps 70' pass around the heads I ofbeam A, and are connected to levers m, that will carry adjustableweights m*. The front roller, D, over which the carpet passes, isprovided with sharp pins for holding the fabric. The winding-roller E isoperated by a pawl, a, hung on the end of a weighted lever, n, which israised by contact ofa projection on the lay-standard a, so that the pawlis caused to act on a ratchet, 0,on the roller when the lever againfalls. The roller D is moved intermittently in the same manner by aweighted lever, 19', carrying two pawls, a, so as to move therollerortake up the length of only a half-notch if that is all that the strainwill permit. The tension caused by lever 11 is always the same, howeverlarge the roll on roller E may be, and the strain being entirely onrollerD the weight on lever n is just enough to roll up the carpet.

Thepicker sticks project through slots in the shuttle-boxes -r and areprovided with pickers 8, made of sole-leather and cupped on the side toreceive the shuttle end, and the sticks pass through loops at the backsof the pickers, whereby the horizontal movements of the pickers arepermitted. The front of each box is formed by a pivoted piece, t, havinga beveled projection at its outer end that is acted on by the picker 3'when the shuttle enters the box, so as to press the front end or portionof the piece 1 inward against the shuttle, thereby locking the shuttlefirmly in the box until the picker starts forward, when the piece t isopened or spread by the spring 1/. on Its outer end.

For operating the loom the lay is provided with a handle, 1/. In theforward position of the lay the warps are straight,the ratchet-wheel hhaving made but a quarter-revolution, and they are strained by the beam0. The weights on levers n p then act to take up the slack caused by theblow of the lay. At the baekward movement of the lay the warps slack,the shed opens, the shuttle is thrown, and levers n p are raised, sothat the pawls a a move down and engage again.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

l. The combination of crank-shaft f, pitmen g heddles B, ratchet h,pawls k, arms i, straps Z, and slide-bar m, substantially as described,for operation as specified.

2. The combination of pivoted beam e, arms 9, posts h, springs i, andslide-bar m, substantially as and for the purpose specified.
